Erosion Research arcing tungsten sheet contact materials

Arc erosion refers to the electric arc , the contact material to escape electronic , metal ions, metal vapor , droplets of molten metal from the electrode surface into the gap, resulting in loss of material . Arc erosion process is very complex , in the electric arc , electrical contact surfaces for physical and chemical changes . Erosion Research arcing contact materials is an important aspect of electrical arcing and contact theory and applied research . Materials production processes,  tungsten carbide plate  will result in different forms and morphologies arc erosion , anti- erosion ability arc prepared by powder metallurgy tungsten copper contact materials has been studied. In this paper, scanning electron microscopy and spectroscopy analyzer to observe the surface morphology of the fiber  Moly Crucible  arc erosion of tungsten copper contact materials , and studied its arc erosion rate , tungsten, copper contact material prepared in conjunction with powder metallurgy arc erosion compared. Materials and Methods tungsten fibers have a directivity alternative refractory metal powder of tungsten powder , a two-dimensional weaving method with the weft wire , tungsten wire is warp knitted and the copper-tungsten mesh ( wire as small when copper -induced infiltration ) and copper billets , two stacked together , placed into a vacuum sintering furnace for infiltration , you can get the fiber structure of tungsten copper contact materials .
